Decentralized reputation management in a named-function network

ABSTRACT

Various systems and methods for providing decentralized reputation management in a named-function network are described herein. A compute node is configured to access an information centric network (ICN) interest packet from a user device, the ICN interest packet including a function name and a data name; construct a named-function network (NFN) interest packet using the function name; transmit the NFN interest packet to a function provider; receive an NFN data packet with a version of a function corresponding to the function name; construct a named-data network (NDN) interest packet using the data name; receive an NDN data packet with a data value corresponding to the data name; determine that the version of the function is not on a denylist; and initiate execution of the version of the function with the data value in response to determining that the version of the function is not on the denylist.

TECHNICAL FIELD

Embodiments described herein generally relate to data communication and analysis systems and in particular to a decentralized reputation management in a named-function network.

BACKGROUND

Edge computing, at a general level, refers to the transition of compute and storage resources closer to endpoint devices (e.g., consumer computing devices, user equipment, etc.) in order to optimize total cost of ownership, reduce application latency, improve service capabilities, and improve compliance with security or data privacy requirements. Edge computing may, in some scenarios, provide a cloud-like distributed service that offers orchestration and management for applications among many types of storage and compute resources. As a result, some implementations of edge computing have been referred to as the “edge cloud” or the “fog”, as powerful computing resources previously available only in large remote data centers are moved closer to endpoints and made available for use by consumers at the “edge” of the network.

Edge computing use cases in mobile network settings have been developed for integration with multi-access edge computing (MEC) approaches, also known as “mobile edge computing.” MEC approaches are designed to allow application developers and content providers to access computing capabilities and an information technology (IT) service environment in dynamic mobile network settings at the edge of the network. Limited standards have been developed by the European Telecommunications Standards Institute (ETSI) industry specification group (ISG) in an attempt to define common interfaces for operation of MEC systems, platforms, hosts, services, and applications.

Edge computing, MEC, and related technologies attempt to provide reduced latency, increased responsiveness, and more available computing power than offered in traditional cloud network services and wide area network connections. However, the integration of mobility and dynamically launched services to some mobile use and device processing use cases has led to limitations and concerns with orchestration, functional coordination, and resource management, especially in complex mobility settings where many participants (devices, hosts, tenants, service providers, operators) are involved. In a similar manner, Internet of Things (IoT) networks and devices are designed to offer a distributed compute arrangement, from a variety of endpoints. IoT devices are physical or virtualized objects that may communicate on a network, and may include sensors, actuators, and other input/output components, which may be used to collect data or perform actions in a real world environment. For example, IoT devices may include low-powered endpoint devices that are embedded or attached to everyday things, such as buildings, vehicles, packages, etc., to provide an additional level of artificial sensory perception of those things. Recently, IoT devices have become more popular and thus applications using these devices have proliferated.

The deployment of various Edge, Fog, MEC, and IoT networks, devices, and services have introduced a number of advanced use cases and scenarios occurring at and towards the edge of the network.

DETAILED DESCRIPTION

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of some example embodiments. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details.

Information centric networking (ICN) is a transport layer or internet layer protocol that is an alternative to address based approaches, such as the Internet Protocol (IP). ICN replaces host addresses with named data (or functions in a named function networking (NFN)). ICN nodes generally include two data structures, a pending interest table (PIT) and a forwarding information base (FIB) that are used for routing.

When data is desired, a requestor releases an interest packet naming the data being sought. A receiving ICN node records the interest packet arrival along with the physical interface upon which the interest was received in a PIT entry. The ICN node uses the FIB to determine upon which physical interface to forward the interest. When a node has data that matches the name of the interest packet, such a node generally responds to the interest packet in a data packet (e.g., ICN data packet). When the data packet arrives at an interim node, that node matches the name of the data packet with a PIT entry and uses the physical interface of the PIT entry to forward the data; the PIT entry being removed once the data packet is sent.

Because only the name of the data is necessary, data may be cached throughout the network without orchestration present in host-based techniques. Thus, as a data packet traverses an interim ICN node, that node may cache the data packet to respond to future requests for the same data.

NFN (Named-Function Networking) is an extension of Information Centric Networking (ICN) that performs in-network resolution of expressions instead of mere content retrieval of a single name, as in ICN. Named-Data Networking (NDN) is similar to ICN where applications request data by its name in an interest packet and communications are data-centric. In ICN/NDN, data chunks have names bound to them. The main service provides name resolution to obtain the data. NFN is similar and extends the service to also resolve computation expressions composed of named data and functions. The name resolution is transparent to the client and allows for simpler interfaces. Use of NFN also disengages functions from function providers so that the provider is not the sole basis for choosing a particular function. Because functions act on data, NFNs and NDNs may be used together so that data is requested by name from an NDN is used as input to a function requested by name from an NFN.

For an NFN, NDN, or ICN to work, the data sources have to be trusted by the clients or requesters. In an NFN, there can be multiple providers of the same function and data. Some of these providers may store stale or outdated artifacts and they may have inadvertently kept the artifacts available for NFN consumers. This problem is amplified in environments where there are multiple providers, each with different versions of a similar function that may have different characteristics. The functions may require different resources to execute upon, the cost and service level agreements (SLA) may be different for variations of functions, and there may be location restrictions on where certain functions can be executed. There is a need to ensure that the data or functions stored in an NFN or ICN are up-to-date, legitimate, and accurately represented.

The present systems and techniques described herein provide a mechanism to track reputable functions in an NFN. Those that are not reputable are added to a denylist (also referred to as a blocklist or a disallowlist). The denylist is an access control mechanism that allows for all elements except for those that are expressly included in the denylist. The denylist is hosted on an NFN router (node) and referenced by the NFN router before returning a function to a requesting client. The denylist may be distributed to avoid a single point of failure and performance bottlenecks that can occur due to a centralized repository. The distributed denylist is also more scalable.

To enhance security and other aspects, the denylist may be implemented using a blockchain. In such an example, the NFN routers are nodes in the blockchain. Another extension includes the use of a permitlist (also referred to as allowlist or passlist). The permitlist is used to expressly list those elements that have access or are accessible. NFN nodes may refer to either the permitlist or the denylist, or both, when determining which function to return or execute in response to a request from a client. Further details are provided in the examples and figures described below.

FIG. 1 is a block diagram 100 showing an overview of a configuration for Edge computing, which includes a layer of processing referred to in many of the following examples as an “Edge cloud”. As shown, the Edge cloud 110 is co-located at an Edge location, such as an access point or base station 140, a local processing hub 150, or a central office 120, and thus may include multiple entities, devices, and equipment instances. The Edge cloud 110 is located much closer to the endpoint (consumer and producer) data sources 160 (e.g., autonomous vehicles 161, user equipment 162, business and industrial equipment 163, video capture devices 164, drones 165, smart cities and building devices 166, sensors and IoT devices 167, etc.) than the cloud data center 130. Compute, memory, and storage resources which are offered at the edges in the Edge cloud 110 are critical to providing ultra-low latency response times for services and functions used by the endpoint data sources 160 as well as reduce network backhaul traffic from the Edge cloud 110 toward cloud data center 130 thus improving energy consumption and overall network usages among other benefits.

Compute, memory, and storage are scarce resources, and generally decrease depending on the Edge location (e.g., fewer processing resources being available at consumer endpoint devices, than at a base station, than at a central office). However, the closer that the Edge location is to the endpoint (e.g., user equipment (UE)), the more that space and power is often constrained. Thus, Edge computing attempts to reduce the amount of resources needed for network services, through the distribution of more resources which are located closer both geographically and in network access time. In this manner, Edge computing attempts to bring the compute resources to the workload data where appropriate, or, bring the workload data to the compute resources.

The following describes aspects of an Edge cloud architecture that covers multiple potential deployments and addresses restrictions that some network operators or service providers may have in their own infrastructures. These include, variation of configurations based on the Edge location (because edges at a base station level, for instance, may have more constrained performance and capabilities in a multi-tenant scenario); configurations based on the type of compute, memory, storage, fabric, acceleration, or like resources available to Edge locations, tiers of locations, or groups of locations; the service, security, and management and orchestration capabilities; and related objectives to achieve usability and performance of end services. These deployments may accomplish processing in network layers that may be considered as “near Edge”, “close Edge”, “local Edge”, “middle Edge”, or “far Edge” layers, depending on latency, distance, and timing characteristics.

Edge computing is a developing paradigm where computing is performed at or closer to the “Edge” of a network, typically through the use of a compute platform (e.g., x86 or ARM compute hardware architecture) implemented at base stations, gateways, network routers, or other devices which are much closer to endpoint devices producing and consuming the data. For example, Edge gateway servers may be equipped with pools of memory and storage resources to perform computation in real-time for low latency use-cases (e.g., autonomous driving or video surveillance) for connected client devices. Or as an example, base stations may be augmented with compute and acceleration resources to directly process service workloads for connected user equipment, without further communicating data via backhaul networks. Or as another example, central office network management hardware may be replaced with standardized compute hardware that performs virtualized network functions and offers compute resources for the execution of services and consumer functions for connected devices. Within Edge computing networks, there may be scenarios in services which the compute resource will be “moved” to the data, as well as scenarios in which the data will be “moved” to the compute resource. Or as an example, base station compute, acceleration and network resources can provide services in order to scale to workload demands on an as needed basis by activating dormant capacity (subscription, capacity on demand) in order to manage corner cases, emergencies or to provide longevity for deployed resources over a significantly longer implemented lifecycle.

FIG. 2 illustrates operational layers among endpoints, an Edge cloud, and cloud computing environments. Specifically, FIG. 2 depicts examples of computational use cases 205, utilizing the Edge cloud 110 among multiple illustrative layers of network computing. The layers begin at an endpoint (devices and things) layer 200, which accesses the Edge cloud 110 to conduct data creation, analysis, and data consumption activities. The Edge cloud 110 may span multiple network layers, such as an Edge devices layer 210 having gateways, on-premise servers, or network equipment (nodes 215) located in physically proximate Edge systems; a network access layer 220, encompassing base stations, radio processing units, network hubs, regional data centers (DC), or local network equipment (equipment 225); and any equipment, devices, or nodes located therebetween (in layer 212, not illustrated in detail). The network communications within the Edge cloud 110 and among the various layers may occur via any number of wired or wireless mediums, including via connectivity architectures and technologies not depicted.

Examples of latency, resulting from network communication distance and processing time constraints, may range from less than a millisecond (ms) when among the endpoint layer 200, under 5 ms at the Edge devices layer 210, to even between 10 to 40 ms when communicating with nodes at the network access layer 220. Beyond the Edge cloud 110 are core network 230 and cloud data center 240 layers, each with increasing latency (e.g., between 50-60 ms at the core network layer 230, to 100 or more ms at the cloud data center layer). As a result, operations at a core network data center 235 or a cloud data center 245, with latencies of at least 50 to 100 ms or more, will not be able to accomplish many time-critical functions of the use cases 205. Each of these latency values are provided for purposes of illustration and contrast; it will be understood that the use of other access network mediums and technologies may further reduce the latencies. In some examples, respective portions of the network may be categorized as “close Edge”, “local Edge”, “near Edge”, “middle Edge”, or “far Edge” layers, relative to a network source and destination. For instance, from the perspective of the core network data center 235 or a cloud data center 245, a central office or content data network may be considered as being located within a “near Edge” layer (“near” to the cloud, having high latency values when communicating with the devices and endpoints of the use cases 205), whereas an access point, base station, on-premise server, or network gateway may be considered as located within a “far Edge” layer (“far” from the cloud, having low latency values when communicating with the devices and endpoints of the use cases 205). It will be understood that other categorizations of a particular network layer as constituting a “close”, “local”, “near”, “middle”, or “far” Edge may be based on latency, distance, number of network hops, or other measurable characteristics, as measured from a source in any of the network layers 200-240.

The various use cases 205 may access resources under usage pressure from incoming streams, due to multiple services utilizing the Edge cloud. To achieve results with low latency, the services executed within the Edge cloud 110 balance varying requirements in terms of: (a) Priority (throughput or latency) and Quality of Service (QoS) (e.g., traffic for an autonomous car may have higher priority than a temperature sensor in terms of response time requirement; or, a performance sensitivity/bottleneck may exist at a compute/accelerator, memory, storage, or network resource, depending on the application); (b) Reliability and Resiliency (e.g., some input streams need to be acted upon and the traffic routed with mission-critical reliability, where as some other input streams may be tolerate an occasional failure, depending on the application); and (c) Physical constraints (e.g., power, cooling and form-factor).

The end-to-end service view for these use cases involves the concept of a service-flow and is associated with a transaction. The transaction details the overall service requirement for the entity consuming the service, as well as the associated services for the resources, workloads, workflows, and business functional and business level requirements. The services executed with the “terms” described may be managed at each layer in a way to assure real time, and runtime contractual compliance for the transaction during the lifecycle of the service. When a component in the transaction is missing its agreed to SLA, the system as a whole (components in the transaction) may provide the ability to (1) understand the impact of the SLA violation, and (2) augment other components in the system to resume overall transaction SLA, and (3) implement steps to remediate.

Thus, with these variations and service features in mind, Edge computing within the Edge cloud 110 may provide the ability to serve and respond to multiple applications of the use cases 205 (e.g., object tracking, video surveillance, connected cars, etc.) in real-time or near real-time, and meet ultra-low latency requirements for these multiple applications. These advantages enable a whole new class of applications (Virtual Network Functions (VNFs), Function as a Service (FaaS), Edge as a Service (EaaS), standard processes, etc.), which cannot leverage conventional cloud computing due to latency or other limitations.

However, with the advantages of Edge computing comes the following caveats. The devices located at the Edge are often resource constrained and therefore there is pressure on usage of Edge resources. Typically, this is addressed through the pooling of memory and storage resources for use by multiple users (tenants) and devices. The Edge may be power and cooling constrained and therefore the power usage needs to be accounted for by the applications that are consuming the most power. There may be inherent power-performance tradeoffs in these pooled memory resources, as many of them are likely to use emerging memory technologies, where more power requires greater memory bandwidth. Likewise, improved security of hardware and root of trust trusted functions are also required, because Edge locations may be unmanned and may even need permissioned access (e.g., when housed in a third-party location). Such issues are magnified in the Edge cloud 110 in a multi-tenant, multi-owner, or multi-access setting, where services and applications are requested by many users, especially as network usage dynamically fluctuates and the composition of the multiple stakeholders, use cases, and services changes.

At a more generic level, an Edge computing system may be described to encompass any number of deployments at the previously discussed layers operating in the Edge cloud 110 (network layers 200-240), which provide coordination from client and distributed computing devices. One or more Edge gateway nodes, one or more Edge aggregation nodes, and one or more core data centers may be distributed across layers of the network to provide an implementation of the Edge computing system by or on behalf of a telecommunication service provider (“telco”, or “TSP”), internet-of-things service provider, cloud service provider (CSP), enterprise entity, or any other number of entities. Various implementations and configurations of the Edge computing system may be provided dynamically, such as when orchestrated to meet service objectives.

Consistent with the examples provided herein, a client compute node may be embodied as any type of endpoint component, device, appliance, or other thing capable of communicating as a producer or consumer of data. Further, the label “node” or “device” as used in the Edge computing system does not necessarily mean that such node or device operates in a client or agent/minion/follower role; rather, any of the nodes or devices in the Edge computing system refer to individual entities, nodes, or subsystems which include discrete or connected hardware or software configurations to facilitate or use the Edge cloud 110.

As such, the Edge cloud 110 is formed from network components and functional features operated by and within Edge gateway nodes, Edge aggregation nodes, or other Edge compute nodes among network layers 210-230. The Edge cloud 110 thus may be embodied as any type of network that provides Edge computing and/or storage resources which are proximately located to radio access network (RAN) capable endpoint devices (e.g., mobile computing devices, IoT devices, smart devices, etc.), which are discussed herein. In other words, the Edge cloud 110 may be envisioned as an “Edge” which connects the endpoint devices and traditional network access points that serve as an ingress point into service provider core networks, including mobile carrier networks (e.g., Global System for Mobile Communications (GSM) networks, Long-Term Evolution (LTE) networks, 5G/6G networks, etc.), while also providing storage and/or compute capabilities. Other types and forms of network access (e.g., Wi-Fi, long-range wireless, wired networks including optical networks) may also be utilized in place of or in combination with such 3GPP carrier networks.

The network components of the Edge cloud 110 may be servers, multi-tenant servers, appliance computing devices, and/or any other type of computing devices. For example, the Edge cloud 110 may include an appliance computing device that is a self-contained electronic device including a housing, a chassis, a case or a shell. In some circumstances, the housing may be dimensioned for portability such that it can be carried by a human and/or shipped. Example housings may include materials that form one or more exterior surfaces that partially or fully protect contents of the appliance, in which protection may include weather protection, hazardous environment protection (e.g., EMI, vibration, extreme temperatures), and/or enable submergibility. Example housings may include power circuitry to provide power for stationary and/or portable implementations, such as AC power inputs, DC power inputs, AC/DC or DC/AC converter(s), power regulators, transformers, charging circuitry, batteries, wired inputs and/or wireless power inputs. Example housings and/or surfaces thereof may include or connect to mounting hardware to enable attachment to structures such as buildings, telecommunication structures (e.g., poles, antenna structures, etc.) and/or racks (e.g., server racks, blade mounts, etc.). Example housings and/or surfaces thereof may support one or more sensors (e.g., temperature sensors, vibration sensors, light sensors, acoustic sensors, capacitive sensors, proximity sensors, etc.). One or more such sensors may be contained in, carried by, or otherwise embedded in the surface and/or mounted to the surface of the appliance. Example housings and/or surfaces thereof may support mechanical connectivity, such as propulsion hardware (e.g., wheels, propellers, etc.) and/or articulating hardware (e.g., robot arms, pivotable appendages, etc.). In some circumstances, the sensors may include any type of input devices such as user interface hardware (e.g., buttons, switches, dials, sliders, etc.). In some circumstances, example housings include output devices contained in, carried by, embedded therein and/or attached thereto. Output devices may include displays, touchscreens, lights, LEDs, speakers, I/O ports (e.g., USB), etc. In some circumstances, Edge devices are devices presented in the network for a specific purpose (e.g., a traffic light), but may have processing and/or other capacities that may be utilized for other purposes. Such Edge devices may be independent from other networked devices and may be provided with a housing having a form factor suitable for its primary purpose; yet be available for other compute tasks that do not interfere with its primary task. Edge devices include Internet of Things devices. The appliance computing device may include hardware and software components to manage local issues such as device temperature, vibration, resource utilization, updates, power issues, physical and network security, etc. Example hardware for implementing an appliance computing device is described in conjunction with FIG. 6B. The Edge cloud 110 may also include one or more servers and/or one or more multi-tenant servers. Such a server may include an operating system and implement a virtual computing environment. A virtual computing environment may include a hypervisor managing (e.g., spawning, deploying, destroying, etc.) one or more virtual machines, one or more containers, etc. Such virtual computing environments provide an execution environment in which one or more applications and/or other software, code or scripts may execute while being isolated from one or more other applications, software, code or scripts.

In FIG. 3 , various client endpoints 310 (in the form of mobile devices, computers, autonomous vehicles, business computing equipment, industrial processing equipment) exchange requests and responses that are specific to the type of endpoint network aggregation. For instance, client endpoints 310 may obtain network access via a wired broadband network, by exchanging requests and responses 322 through an on-premise network system 332. Some client endpoints 310, such as mobile computing devices, may obtain network access via a wireless broadband network, by exchanging requests and responses 324 through an access point (e.g., cellular network tower) 334. Some client endpoints 310, such as autonomous vehicles may obtain network access for requests and responses 326 via a wireless vehicular network through a street-located network system 336. However, regardless of the type of network access, the TSP may deploy aggregation points 342, 344 within the Edge cloud 110 to aggregate traffic and requests. Thus, within the Edge cloud 110, the TSP may deploy various compute and storage resources, such as at Edge aggregation nodes 340, to provide requested content. The Edge aggregation nodes 340 and other systems of the Edge cloud 110 are connected to a cloud or data center 360, which uses a backhaul network 350 to fulfill higher-latency requests from a cloud/data center for websites, applications, database servers, etc. Additional or consolidated instances of the Edge aggregation nodes 340 and the aggregation points 342, 344, including those deployed on a single server framework, may also be present within the Edge cloud 110 or other areas of the TSP infrastructure.

FIG. 4 illustrates deployment and orchestration for virtualized and container-based Edge configurations across an Edge computing system operated among multiple Edge nodes and multiple tenants (e.g., users, providers) which use such Edge nodes. Specifically, FIG. 4 depicts coordination of a first Edge node 422 and a second Edge node 424 in an Edge computing system 400, to fulfill requests and responses for various client endpoints 410 (e.g., smart cities/building systems, mobile devices, computing devices, business/logistics systems, industrial systems, etc.), which access various virtual Edge instances. Here, the virtual Edge instances 432, 434 provide Edge compute capabilities and processing in an Edge cloud, with access to a cloud/data center 440 for higher-latency requests for websites, applications, database servers, etc. However, the Edge cloud enables coordination of processing among multiple Edge nodes for multiple tenants or entities.

In the example of FIG. 4 , these virtual Edge instances include: a first virtual Edge 432, offered to a first tenant (Tenant 1), which offers a first combination of Edge storage, computing, and services; and a second virtual Edge 434, offering a second combination of Edge storage, computing, and services. The virtual Edge instances 432, 434 are distributed among the Edge nodes 422, 424, and may include scenarios in which a request and response are fulfilled from the same or different Edge nodes. The configuration of the Edge nodes 422, 424 to operate in a distributed yet coordinated fashion occurs based on Edge provisioning functions 450. The functionality of the Edge nodes 422, 424 to provide coordinated operation for applications and services, among multiple tenants, occurs based on orchestration functions 460.

It should be understood that some of the devices in 410 are multi-tenant devices where Tenant 1 may function within a tenant1 ‘slice’ while a Tenant 2 may function within a tenant2 slice (and, in further examples, additional or sub-tenants may exist; and each tenant may even be specifically entitled and transactionally tied to a specific set of features all the way day to specific hardware features). A trusted multi-tenant device may further contain a tenant specific cryptographic key such that the combination of key and slice may be considered a “root of trust” (RoT) or tenant specific RoT. A RoT may further be computed dynamically composed using a DICE (Device Identity Composition Engine) architecture such that a single DICE hardware building block may be used to construct layered trusted computing base contexts for layering of device capabilities (such as a Field Programmable Gate Array (FPGA)). The RoT may further be used for a trusted computing context to enable a “fan-out” that is useful for supporting multi-tenancy. Within a multi-tenant environment, the respective Edge nodes 422, 424 may operate as security feature enforcement points for local resources allocated to multiple tenants per node. Additionally, tenant runtime and application execution (e.g., in instances 432, 434) may serve as an enforcement point for a security feature that creates a virtual Edge abstraction of resources spanning potentially multiple physical hosting platforms. Finally, the orchestration functions 460 at an orchestration entity may operate as a security feature enforcement point for marshalling resources along tenant boundaries.

Edge computing nodes may partition resources (memory, central processing unit (CPU), graphics processing unit (GPU), interrupt controller, input/output (I/O) controller, memory controller, bus controller, etc.) where respective partitionings may contain a RoT capability and where fan-out and layering according to a DICE model may further be applied to Edge Nodes. Cloud computing nodes often use containers, FaaS engines, Servlets, servers, or other computation abstraction that may be partitioned according to a DICE layering and fan-out structure to support a RoT context for each. Accordingly, the respective RoTs spanning devices 410, 422, and 440 may coordinate the establishment of a distributed trusted computing base (DTCB) such that a tenant-specific virtual trusted secure channel linking all elements end to end can be established.

Further, it will be understood that a container may have data or workload specific keys protecting its content from a previous Edge node. As part of migration of a container, a pod controller at a source Edge node may obtain a migration key from a target Edge node pod controller where the migration key is used to wrap the container-specific keys. When the container/pod is migrated to the target Edge node, the unwrapping key is exposed to the pod controller that then decrypts the wrapped keys. The keys may now be used to perform operations on container specific data. The migration functions may be gated by properly attested Edge nodes and pod managers (as described above).

In further examples, an Edge computing system is extended to provide for orchestration of multiple applications through the use of containers (a contained, deployable unit of software that provides code and needed dependencies) in a multi-owner, multi-tenant environment. A multi-tenant orchestrator may be used to perform key management, trust anchor management, and other security functions related to the provisioning and lifecycle of the trusted ‘slice’ concept in FIG. 4 . For instance, an Edge computing system may be configured to fulfill requests and responses for various client endpoints from multiple virtual Edge instances (and, from a cloud or remote data center). The use of these virtual Edge instances may support multiple tenants and multiple applications (e.g., augmented reality (AR)/virtual reality (VR), enterprise applications, content delivery, gaming, compute offload) simultaneously. Further, there may be multiple types of applications within the virtual Edge instances (e.g., normal applications; latency sensitive applications; latency-critical applications; user plane applications; networking applications; etc.). The virtual Edge instances may also be spanned across systems of multiple owners at different geographic locations (or, respective computing systems and resources which are co-owned or co-managed by multiple owners).

For instance, each Edge node 422, 424 may implement the use of containers, such as with the use of a container “pod” 426, 428 providing a group of one or more containers. In a setting that uses one or more container pods, a pod controller or orchestrator is responsible for local control and orchestration of the containers in the pod. Various Edge node resources (e.g., storage, compute, services, depicted with hexagons) provided for the respective Edge slices 432, 434 are partitioned according to the needs of each container.

With the use of container pods, a pod controller oversees the partitioning and allocation of containers and resources. The pod controller receives instructions from an orchestrator (e.g., orchestrator 460) that instructs the controller on how best to partition physical resources and for what duration, such as by receiving key performance indicator (KPI) targets based on SLA contracts. The pod controller determines which container requires which resources and for how long in order to complete the workload and satisfy the SLA. The pod controller also manages container lifecycle operations such as: creating the container, provisioning it with resources and applications, coordinating intermediate results between multiple containers working on a distributed application together, dismantling containers when workload completes, and the like. Additionally, a pod controller may serve a security role that prevents assignment of resources until the right tenant authenticates or prevents provisioning of data or a workload to a container until an attestation result is satisfied.

Also, with the use of container pods, tenant boundaries can still exist but in the context of each pod of containers. If each tenant specific pod has a tenant specific pod controller, there will be a shared pod controller that consolidates resource allocation requests to avoid typical resource starvation situations. Further controls may be provided to ensure attestation and trustworthiness of the pod and pod controller. For instance, the orchestrator 460 may provision an attestation verification policy to local pod controllers that perform attestation verification. If an attestation satisfies a policy for a first tenant pod controller but not a second tenant pod controller, then the second pod could be migrated to a different Edge node that does satisfy it. Alternatively, the first pod may be allowed to execute and a different shared pod controller is installed and invoked prior to the second pod executing.

FIG. 5 illustrates additional compute arrangements deploying containers in an Edge computing system. As a simplified example, system arrangements 510, 520 depict settings in which a pod controller (e.g., container managers 511, 521, and container orchestrator 531) is adapted to launch containerized pods, functions, and functions-as-a-service instances through execution via compute nodes (515 in arrangement 510), or to separately execute containerized virtualized network functions through execution via compute nodes (523 in arrangement 520). This arrangement is adapted for use of multiple tenants in system arrangement 530 (using compute nodes 537), where containerized pods (e.g., pods 512), functions (e.g., functions 513, VNFs 522, 536), and functions-as-a-service instances (e.g., FaaS instance 514) are launched within virtual machines (e.g., VMs 534, 535 for tenants 532, 533) specific to respective tenants (aside the execution of virtualized network functions). This arrangement is further adapted for use in system arrangement 540, which provides containers 542, 543, or execution of the various functions, applications, and functions on compute nodes 544, as coordinated by an container-based orchestration system 541.

The system arrangements of depicted in FIG. 5 provides an architecture that treats VMs, Containers, and Functions equally in terms of application composition (and resulting applications are combinations of these three ingredients). Each ingredient may involve use of one or more accelerator (FPGA, ASIC) components as a local backend. In this manner, applications can be split across multiple Edge owners, coordinated by an orchestrator.

In the context of FIG. 5 , the pod controller/container manager, container orchestrator, and individual nodes may provide a security enforcement point. However, tenant isolation may be orchestrated where the resources allocated to a tenant are distinct from resources allocated to a second tenant, but Edge owners cooperate to ensure resource allocations are not shared across tenant boundaries. Or, resource allocations could be isolated across tenant boundaries, as tenants could allow “use” via a subscription or transaction/contract basis. In these contexts, virtualization, containerization, enclaves and hardware partitioning schemes may be used by Edge owners to enforce tenancy. Other isolation environments may include: bare metal (dedicated) equipment, virtual machines, containers, virtual machines on containers, or combinations thereof.

In further examples, aspects of software-defined or controlled silicon hardware, and other configurable hardware, may integrate with the applications, functions, and services an Edge computing system. Software defined silicon (SDSi) may be used to ensure the ability for some resource or hardware ingredient to fulfill a contract or service level agreement, based on the ingredient's ability to remediate a portion of itself or the workload (e.g., by an upgrade, reconfiguration, or provision of new features within the hardware configuration itself).

In further examples, any of the compute nodes or devices discussed with reference to the present Edge computing systems and environment may be fulfilled based on the components depicted in FIGS. 6A and 6B. Respective Edge compute nodes may be embodied as a type of device, appliance, computer, or other “thing” capable of communicating with other Edge, networking, or endpoint components. For example, an Edge compute device may be embodied as a personal computer, server, smartphone, a mobile compute device, a smart appliance, an in-vehicle compute system (e.g., a navigation system), a self-contained device having an outer case, shell, etc., or other device or system capable of performing the described functions.

In the simplified example depicted in FIG. 6A, an Edge compute node 600 includes a compute engine (also referred to herein as “compute circuitry”) 602, an input/output (I/O) subsystem (also referred to herein as “I/O circuitry”) 608, data storage (also referred to herein as “data storage circuitry”) 610, a communication circuitry subsystem 612, and, optionally, one or more peripheral devices (also referred to herein as “peripheral device circuitry”) 614. In other examples, respective compute devices may include other or additional components, such as those typically found in a computer (e.g., a display, peripheral devices, etc.). Additionally, in some examples, one or more of the illustrative components may be incorporated in, or otherwise form a portion of, another component.

The compute node 600 may be embodied as any type of engine, device, or collection of devices capable of performing various compute functions. In some examples, the compute node 600 may be embodied as a single device such as an integrated circuit, an embedded system, a field-programmable gate array (FPGA), a system-on-a-chip (SOC), or other integrated system or device. In the illustrative example, the compute node 600 includes or is embodied as a processor (also referred to herein as “processor circuitry”) 604 and a memory (also referred to herein as “memory circuitry”) 606. The processor 604 may be embodied as any type of processor(s) capable of performing the functions described herein (e.g., executing an application). For example, the processor 604 may be embodied as a multi-core processor(s), a microcontroller, a processing unit, a specialized or special purpose processing unit, or other processor or processing/controlling circuit.

In some examples, the processor 604 may be embodied as, include, or be coupled to an FPGA, an application specific integrated circuit (ASIC), reconfigurable hardware or hardware circuitry, or other specialized hardware to facilitate performance of the functions described herein. Also in some examples, the processor 604 may be embodied as a specialized x-processing unit (xPU) also known as a data processing unit (DPU), infrastructure processing unit (IPU), or network processing unit (NPU). Such an xPU may be embodied as a standalone circuit or circuit package, integrated within an SOC, or integrated with networking circuitry (e.g., in a SmartNIC, or enhanced SmartNIC), acceleration circuitry, storage devices, storage disks, or AI hardware (e.g., GPUs or programmed FPGAs). Such an xPU may be designed to receive, retrieve and/or otherwise obtain programming to process one or more data streams and perform specific tasks and actions for the data streams (such as hosting microservices, performing service management or orchestration, organizing or managing server or data center hardware, managing service meshes, or collecting and distributing telemetry), outside of the CPU or general purpose processing hardware. However, it will be understood that a xPU, a SOC, a CPU, and other variations of the processor 604 may work in coordination with each other to execute many types of operations and instructions within and on behalf of the compute node 600.

The memory 606 may be embodied as any type of volatile (e.g., dynamic random access memory (DRAM), etc.) or non-volatile memory or data storage capable of performing the functions described herein. Volatile memory may be a storage medium that requires power to maintain the state of data stored by the medium. Non-limiting examples of volatile memory may include various types of random access memory (RAM), such as DRAM or static random access memory (SRAM). One particular type of DRAM that may be used in a memory module is synchronous dynamic random access memory (SDRAM).

In an example, the memory device (e.g., memory circuitry) is any number of block addressable memory devices, such as those based on NAND or NOR technologies (for example, Single-Level Cell (“SLC”), Multi-Level Cell (“MLC”), Quad-Level Cell (“QLC”), Tri-Level Cell (“TLC”), or some other NAND). In some examples, the memory device(s) includes a byte-addressable write-in-place three dimensional crosspoint memory device, or other byte addressable write-in-place non-volatile memory (NVM) devices, such as single or multi-level Phase Change Memory (PCM) or phase change memory with a switch (PCMS), NVM devices that use chalcogenide phase change material (for example, chalcogenide glass), resistive memory including metal oxide base, oxygen vacancy base and Conductive Bridge Random Access Memory (CB-RAM), nanowire memory, ferroelectric transistor random access memory (FeTRAM), magneto resistive random access memory (MRAM) that incorporates memristor technology, spin transfer torque (STT)-MRAM, a spintronic magnetic junction memory based device, a magnetic tunneling junction (MTJ) based device, a DW (Domain Wall) and SOT (Spin Orbit Transfer) based device, a thyristor based memory device, a combination of any of the above, or other suitable memory. A memory device may also include a three-dimensional crosspoint memory device (e.g., Intel® 3D XPoint™ memory), or other byte addressable write-in-place nonvolatile memory devices. The memory device may refer to the die itself and/or to a packaged memory product. In some examples, 3D crosspoint memory (e.g., Intel® 3D XPoint™ memory) may include a transistor-less stackable cross point architecture in which memory cells sit at the intersection of word lines and bit lines and are individually addressable and in which bit storage is based on a change in bulk resistance. In some examples, all or a portion of the memory 606 may be integrated into the processor 604. The memory 606 may store various software and data used during operation such as one or more applications, data operated on by the application(s), libraries, and drivers.

In some examples, resistor-based and/or transistor-less memory architectures include nanometer scale phase-change memory (PCM) devices in which a volume of phase-change material resides between at least two electrodes. Portions of the example phase-change material exhibit varying degrees of crystalline phases and amorphous phases, in which varying degrees of resistance between the at least two electrodes can be measured. In some examples, the phase-change material is a chalcogenide-based glass material. Such resistive memory devices are sometimes referred to as memristive devices that remember the history of the current that previously flowed through them. Stored data is retrieved from example PCM devices by measuring the electrical resistance, in which the crystalline phases exhibit a relatively lower resistance value(s) (e.g., logical “0”) when compared to the amorphous phases having a relatively higher resistance value(s) (e.g., logical “1”).

Example PCM devices store data for long periods of time (e.g., approximately 10 years at room temperature). Write operations to example PCM devices (e.g., set to logical “0”, set to logical “1”, set to an intermediary resistance value) are accomplished by applying one or more current pulses to the at least two electrodes, in which the pulses have a particular current magnitude and duration. For instance, a long low current pulse (SET) applied to the at least two electrodes causes the example PCM device to reside in a low-resistance crystalline state, while a comparatively short high current pulse (RESET) applied to the at least two electrodes causes the example PCM device to reside in a high-resistance amorphous state.

In some examples, implementation of PCM devices facilitates non-von Neumann computing architectures that enable in-memory computing capabilities. Generally speaking, traditional computing architectures include a central processing unit (CPU) communicatively connected to one or more memory devices via a bus. As such, a finite amount of energy and time is consumed to transfer data between the CPU and memory, which is a known bottleneck of von Neumann computing architectures. However, PCM devices minimize and, in some cases, eliminate data transfers between the CPU and memory by performing some computing operations in-memory. Stated differently, PCM devices both store information and execute computational tasks. Such non-von Neumann computing architectures may implement vectors having a relatively high dimensionality to facilitate hyperdimensional computing, such as vectors having 10,000 bits. Relatively large bit width vectors enable computing paradigms modeled after the human brain, which also processes information analogous to wide bit vectors.

The compute circuitry 602 is communicatively coupled to other components of the compute node 600 via the I/O subsystem 608, which may be embodied as circuitry and/or components to facilitate input/output operations with the compute circuitry 602 (e.g., with the processor 604 and/or the main memory 606) and other components of the compute circuitry 602. For example, the I/O subsystem 608 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, integrated sensor hubs, firmware devices, communication links (e.g., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.), and/or other components and subsystems to facilitate the input/output operations. In some examples, the I/O subsystem 608 may form a portion of a system-on-a-chip (SoC) and be incorporated, along with one or more of the processor 604, the memory 606, and other components of the compute circuitry 602, into the compute circuitry 602.

The one or more illustrative data storage devices/disks 610 may be embodied as one or more of any type(s) of physical device(s) configured for short-term or long-term storage of data such as, for example, memory devices, memory, circuitry, memory cards, flash memory, hard disk drives, solid-state drives (SSDs), and/or other data storage devices/disks. Individual data storage devices/disks 610 may include a system partition that stores data and firmware code for the data storage device/disk 610. Individual data storage devices/disks 610 may also include one or more operating system partitions that store data files and executables for operating systems depending on, for example, the type of compute node 600.

The communication circuitry 612 may be embodied as any communication circuit, device, or collection thereof, capable of enabling communications over a network between the compute circuitry 602 and another compute device (e.g., an Edge gateway of an implementing Edge computing system). The communication circuitry 612 may be configured to use any one or more communication technology (e.g., wired or wireless communications) and associated protocols (e.g., a cellular networking protocol such a 3GPP 4G or 5G standard, a wireless local area network protocol such as IEEE 802.11/Wi-Fi®, a wireless wide area network protocol, Ethernet, Bluetooth®, Bluetooth Low Energy, a IoT protocol such as IEEE 802.15.4 or ZigBee®, low-power wide-area network (LPWAN) or low-power wide-area (LPWA) protocols, etc.) to effect such communication.

The illustrative communication circuitry 612 includes a network interface controller (NIC) 620, which may also be referred to as a host fabric interface (HFI). The NIC 620 may be embodied as one or more add-in-boards, daughter cards, network interface cards, controller chips, chipsets, or other devices that may be used by the compute node 600 to connect with another compute device (e.g., an Edge gateway node). In some examples, the NIC 620 may be embodied as part of a system-on-a-chip (SoC) that includes one or more processors, or included on a multichip package that also contains one or more processors. In some examples, the NIC 620 may include a local processor (not shown) and/or a local memory (not shown) that are both local to the NIC 620. In such examples, the local processor of the NIC 620 may be capable of performing one or more of the functions of the compute circuitry 602 described herein. Additionally, or alternatively, in such examples, the local memory of the NIC 620 may be integrated into one or more components of the client compute node at the board level, socket level, chip level, and/or other levels.

Additionally, in some examples, a respective compute node 600 may include one or more peripheral devices 614. Such peripheral devices 614 may include any type of peripheral device found in a compute device or server such as audio input devices, a display, other input/output devices, interface devices, and/or other peripheral devices, depending on the particular type of the compute node 600. In further examples, the compute node 600 may be embodied by a respective Edge compute node (whether a client, gateway, or aggregation node) in an Edge computing system or like forms of appliances, computers, subsystems, circuitry, or other components.

In a more detailed example, FIG. 6B illustrates a block diagram of an example of components that may be present in an Edge computing node 650 for implementing the techniques (e.g., operations, processes, methods, and methodologies) described herein. This Edge computing node 650 provides a closer view of the respective components of node 600 when implemented as or as part of a computing device (e.g., as a mobile device, a base station, server, gateway, etc.). The Edge computing node 650 may include any combination of the hardware or logical components referenced herein, and it may include or couple with any device usable with an Edge communication network or a combination of such networks. The components may be implemented as integrated circuits (ICs), portions thereof, discrete electronic devices, or other modules, instruction sets, programmable logic or algorithms, hardware, hardware accelerators, software, firmware, or a combination thereof adapted in the Edge computing node 650, or as components otherwise incorporated within a chassis of a larger system.

The Edge computing device 650 may include processing circuitry in the form of a processor 652, which may be a microprocessor, a multi-core processor, a multithreaded processor, an ultra-low voltage processor, an embedded processor, an xPU/DPU/IPU/NPU, special purpose processing unit, specialized processing unit, or other known processing elements. The processor 652 may be a part of a system on a chip (SoC) in which the processor 652 and other components are formed into a single integrated circuit, or a single package, such as the Edison™ or Galileo™ SoC boards from Intel Corporation, Santa Clara, Calif. As an example, the processor 652 may include an Intel® Architecture Core™ based CPU processor, such as a Quark™, an Atom™, an i3, an i5, an i7, an i9, or an MCU-class processor, or another such processor available from Intel®. However, any number other processors may be used, such as available from Advanced Micro Devices, Inc. (AMD®) of Sunnyvale, Calif., a MIPS®-based design from MIPS Technologies, Inc. of Sunnyvale, Calif., an ARM®-based design licensed from ARM Holdings, Ltd. or a customer thereof, or their licensees or adopters. The processors may include units such as an A5-A13 processor from Apple® Inc., a Snapdragon™ processor from Qualcomm® Technologies, Inc., or an OMAP™ processor from Texas Instruments, Inc. The processor 652 and accompanying circuitry may be provided in a single socket form factor, multiple socket form factor, or a variety of other formats, including in limited hardware configurations or configurations that include fewer than all elements shown in FIG. 6B.

The processor 652 may communicate with a system memory 654 over an interconnect 656 (e.g., a bus). Any number of memory devices may be used to provide for a given amount of system memory. As examples, the memory 654 may be random access memory (RAM) in accordance with a Joint Electron Devices Engineering Council (JEDEC) design such as the DDR or mobile DDR standards (e.g., LPDDR, LPDDR2, LPDDR3, or LPDDR4). In particular examples, a memory component may comply with a DRAM standard promulgated by JEDEC, such as JESD79F for DDR SDRAM, JESD79-2F for DDR2 SDRAM, JESD79-3F for DDR3 SDRAM, JESD79-4A for DDR4 SDRAM, JESD209 for Low Power DDR (LPDDR), JESD209-2 for LPDDR2, JESD209-3 for LPDDR3, and JESD209-4 for LPDDR4. Such standards (and similar standards) may be referred to as DDR-based standards and communication interfaces of the storage devices that implement such standards may be referred to as DDR-based interfaces. In various implementations, the individual memory devices may be of any number of different package types such as single die package (SDP), dual die package (DDP) or quad die package (Q17P). These devices, in some examples, may be directly soldered onto a motherboard to provide a lower profile solution, while in other examples the devices are configured as one or more memory modules that in turn couple to the motherboard by a given connector. Any number of other memory implementations may be used, such as other types of memory modules, e.g., dual inline memory modules (DIMMs) of different varieties including but not limited to microDIMMs or MiniDIMMs.

To provide for persistent storage of information such as data, applications, operating systems and so forth, a storage 658 may also couple to the processor 652 via the interconnect 656. In an example, the storage 658 may be implemented via a solid-state disk drive (SSDD). Other devices that may be used for the storage 658 include flash memory cards, such as Secure Digital (SD) cards, microSD cards, eXtreme Digital (XD) picture cards, and the like, and Universal Serial Bus (USB) flash drives. In an example, the memory device may be or may include memory devices that use chalcogenide glass, multi-threshold level NAND flash memory, NOR flash memory, single or multi-level Phase Change Memory (PCM), a resistive memory, nanowire memory, ferroelectric transistor random access memory (FeTRAM), anti-ferroelectric memory, magnetoresistive random access memory (MRAM) memory that incorporates memristor technology, resistive memory including the metal oxide base, the oxygen vacancy base and the conductive bridge Random Access Memory (CB-RAM), or spin transfer torque (STT)-MRAM, a spintronic magnetic junction memory based device, a magnetic tunneling junction (MTJ) based device, a DW (Domain Wall) and SOT (Spin Orbit Transfer) based device, a thyristor based memory device, or a combination of any of the above, or other memory.

In low power implementations, the storage 658 may be on-die memory or registers associated with the processor 652. However, in some examples, the storage 658 may be implemented using a micro hard disk drive (HDD). Further, any number of new technologies may be used for the storage 658 in addition to, or instead of, the technologies described, such resistance change memories, phase change memories, holographic memories, or chemical memories, among others.

The components may communicate over the interconnect 656. The interconnect 656 may include any number of technologies, including industry standard architecture (ISA), extended ISA (EISA), peripheral component interconnect (PCI), peripheral component interconnect extended (PCIx), PCI express (PCIe), or any number of other technologies. The interconnect 656 may be a proprietary bus, for example, used in an SoC based system. Other bus systems may be included, such as an Inter-Integrated Circuit (I2C) interface, a Serial Peripheral Interface (SPI) interface, point to point interfaces, and a power bus, among others.

The interconnect 656 may couple the processor 652 to a transceiver 666, for communications with the connected Edge devices 662. The transceiver 666 may use any number of frequencies and protocols, such as 2.4 Gigahertz (GHz) transmissions under the IEEE 802.15.4 standard, using the Bluetooth® low energy (BLE) standard, as defined by the Bluetooth® Special Interest Group, or the ZigBee® standard, among others. Any number of radios, configured for a particular wireless communication protocol, may be used for the connections to the connected Edge devices 662. For example, a wireless local area network (WLAN) unit may be used to implement Wi-Fi® communications in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. In addition, wireless wide area communications, e.g., according to a cellular or other wireless wide area protocol, may occur via a wireless wide area network (WWAN) unit.

The wireless network transceiver 666 (or multiple transceivers) may communicate using multiple standards or radios for communications at a different range. For example, the Edge computing node 650 may communicate with close devices, e.g., within about 10 meters, using a local transceiver based on Bluetooth Low Energy (BLE), or another low power radio, to save power. More distant connected Edge devices 662, e.g., within about 50 meters, may be reached over ZigBee® or other intermediate power radios. Both communications techniques may take place over a single radio at different power levels or may take place over separate transceivers, for example, a local transceiver using BLE and a separate mesh transceiver using ZigBee®.

A wireless network transceiver 666 (e.g., a radio transceiver) may be included to communicate with devices or services in a cloud (e.g., an Edge cloud 695) via local or wide area network protocols. The wireless network transceiver 666 may be a low-power wide-area (LPWA) transceiver that follows the IEEE 802.15.4, or IEEE 802.15.4g standards, among others. The Edge computing node 650 may communicate over a wide area using LoRaWAN™ (Long Range Wide Area Network) developed by Semtech and the LoRa Alliance. The techniques described herein are not limited to these technologies but may be used with any number of other cloud transceivers that implement long range, low bandwidth communications, such as Sigfox, and other technologies. Further, other communications techniques, such as time-slotted channel hopping, described in the IEEE 802.15.4e specification may be used.

Any number of other radio communications and protocols may be used in addition to the systems mentioned for the wireless network transceiver 666, as described herein. For example, the transceiver 666 may include a cellular transceiver that uses spread spectrum (SPA/SAS) communications for implementing high-speed communications. Further, any number of other protocols may be used, such as Wi-Fi® networks for medium speed communications and provision of network communications. The transceiver 666 may include radios that are compatible with any number of 3GPP (Third Generation Partnership Project) specifications, such as Long Term Evolution (LTE) and 5th Generation (5G) communication systems, discussed in further detail at the end of the present disclosure. A network interface controller (NIC) 668 may be included to provide a wired communication to nodes of the Edge cloud 695 or to other devices, such as the connected Edge devices 662 (e.g., operating in a mesh). The wired communication may provide an Ethernet connection or may be based on other types of networks, such as Controller Area Network (CAN), Local Interconnect Network (LIN), DeviceNet, ControlNet, Data Highway+, PROFIBUS, or PROFINET, among many others. An additional NIC 668 may be included to enable connecting to a second network, for example, a first NIC 668 providing communications to the cloud over Ethernet, and a second NIC 668 providing communications to other devices over another type of network.

Given the variety of types of applicable communications from the device to another component or network, applicable communications circuitry used by the device may include or be embodied by any one or more of components 664, 666, 668, or 670. Accordingly, in various examples, applicable means for communicating (e.g., receiving, transmitting, etc.) may be embodied by such communications circuitry.

The Edge computing node 650 may include or be coupled to acceleration circuitry 664, which may be embodied by one or more artificial intelligence (AI) accelerators, a neural compute stick, neuromorphic hardware, an FPGA, an arrangement of GPUs, an arrangement of xPUs/DPUs/IPU/NPUs, one or more SoCs, one or more CPUs, one or more digital signal processors, dedicated ASICs, or other forms of specialized processors or circuitry designed to accomplish one or more specialized tasks. These tasks may include AI processing (including machine learning, training, inferencing, and classification operations), visual data processing, network data processing, object detection, rule analysis, or the like. These tasks also may include the specific Edge computing tasks for service management and service operations discussed elsewhere in this document.

The interconnect 656 may couple the processor 652 to a sensor hub or external interface 670 that is used to connect additional devices or subsystems. The devices may include sensors 672, such as accelerometers, level sensors, flow sensors, optical light sensors, camera sensors, temperature sensors, global navigation system (e.g., GPS) sensors, pressure sensors, barometric pressure sensors, and the like. The hub or interface 670 further may be used to connect the Edge computing node 650 to actuators 674, such as power switches, valve actuators, an audible sound generator, a visual warning device, and the like.

In some optional examples, various input/output (I/O) devices may be present within or connected to, the Edge computing node 650. For example, a display or other output device 684 may be included to show information, such as sensor readings or actuator position. An input device 686, such as a touch screen or keypad may be included to accept input. An output device 684 may include any number of forms of audio or visual display, including simple visual outputs such as binary status indicators (e.g., light-emitting diodes (LEDs)) and multi-character visual outputs, or more complex outputs such as display screens (e.g., liquid crystal display (LCD) screens), with the output of characters, graphics, multimedia objects, and the like being generated or produced from the operation of the Edge computing node 650. A display or console hardware, in the context of the present system, may be used to provide output and receive input of an Edge computing system; to manage components or services of an Edge computing system; identify a state of an Edge computing component or service; or to conduct any other number of management or administration functions or service use cases.

A battery 676 may power the Edge computing node 650, although, in examples in which the Edge computing node 650 is mounted in a fixed location, it may have a power supply coupled to an electrical grid, or the battery may be used as a backup or for temporary capabilities. The battery 676 may be a lithium ion battery, or a metal-air battery, such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, and the like.

A battery monitor/charger 678 may be included in the Edge computing node 650 to track the state of charge (SoCh) of the battery 676, if included. The battery monitor/charger 678 may be used to monitor other parameters of the battery 676 to provide failure predictions, such as the state of health (SoH) and the state of function (SoF) of the battery 676. The battery monitor/charger 678 may include a battery monitoring integrated circuit, such as an LTC4020 or an LTC2990 from Linear Technologies, an ADT7488A from ON Semiconductor of Phoenix Arizona, or an IC from the UCD90xxx family from Texas Instruments of Dallas, Tex. The battery monitor/charger 678 may communicate the information on the battery 676 to the processor 652 over the interconnect 656. The battery monitor/charger 678 may also include an analog-to-digital (ADC) converter that enables the processor 652 to directly monitor the voltage of the battery 676 or the current flow from the battery 676. The battery parameters may be used to determine actions that the Edge computing node 650 may perform, such as transmission frequency, mesh network operation, sensing frequency, and the like.

A power block 680, or other power supply coupled to a grid, may be coupled with the battery monitor/charger 678 to charge the battery 676. In some examples, the power block 680 may be replaced with a wireless power receiver to obtain the power wirelessly, for example, through a loop antenna in the Edge computing node 650. A wireless battery charging circuit, such as an LTC4020 chip from Linear Technologies of Milpitas, Calif., among others, may be included in the battery monitor/charger 678. The specific charging circuits may be selected based on the size of the battery 676, and thus, the current required. The charging may be performed using the Airfuel standard promulgated by the Airfuel Alliance, the Qi wireless charging standard promulgated by the Wireless Power Consortium, or the Rezence charging standard, promulgated by the Alliance for Wireless Power, among others.

The storage 658 may include instructions 682 in the form of software, firmware, or hardware commands to implement the techniques described herein. Although such instructions 682 are shown as code blocks included in the memory 654 and the storage 658, it may be understood that any of the code blocks may be replaced with hardwired circuits, for example, built into an application specific integrated circuit (ASIC).

In an example, the instructions 682 provided via the memory 654, the storage 658, or the processor 652 may be embodied as a non-transitory, machine-readable medium 660 including code to direct the processor 652 to perform electronic operations in the Edge computing node 650. The processor 652 may access the non-transitory, machine-readable medium 660 over the interconnect 656. For instance, the non-transitory, machine-readable medium 660 may be embodied by devices described for the storage 658 or may include specific storage units such as storage devices and/or storage disks that include optical disks (e.g., digital versatile disk (DVD), compact disk (CD), CD-ROM, Blu-ray disk), flash drives, floppy disks, hard drives (e.g., SSDs), or any number of other hardware devices in which information is stored for any duration (e.g., for extended time periods, permanently, for brief instances, for temporarily buffering, and/or caching). The non-transitory, machine-readable medium 660 may include instructions to direct the processor 652 to perform a specific sequence or flow of actions, for example, as described with respect to the flowchart(s) and block diagram(s) of operations and functionality depicted above. As used herein, the terms “machine-readable medium” and “computer-readable medium” are interchangeable. As used herein, the term “non-transitory computer-readable medium” is expressly defined to include any type of computer readable storage device and/or storage disk and to exclude propagating signals and to exclude transmission media.

Also in a specific example, the instructions 682 on the processor 652 (separately, or in combination with the instructions 682 of the machine readable medium 660) may configure execution or operation of a trusted execution environment (TEE) 690. In an example, the TEE 690 operates as a protected area accessible to the processor 652 for secure execution of instructions and secure access to data. Various implementations of the TEE 690, and an accompanying secure area in the processor 652 or the memory 654 may be provided, for instance, through use of Intel® Software Guard Extensions (SGX) or ARM® TrustZone® hardware security extensions, Intel® Management Engine (ME), or Intel® Converged Security Manageability Engine (CSME). Other aspects of security hardening, hardware roots-of-trust, and trusted or protected operations may be implemented in the device 650 through the TEE 690 and the processor 652.

While the illustrated examples of FIG. 6A and FIG. 6B include example components for a compute node and a computing device, respectively, examples disclosed herein are not limited thereto. As used herein, a “computer” may include some or all of the example components of FIGS. 6A and/or 6B in different types of computing environments. Example computing environments include Edge computing devices (e.g., Edge computers) in a distributed networking arrangement such that particular ones of participating Edge computing devices are heterogenous or homogeneous devices. As used herein, a “computer” may include a personal computer, a server, user equipment, an accelerator, etc., including any combinations thereof. In some examples, distributed networking and/or distributed computing includes any number of such Edge computing devices as illustrated in FIGS. 6A and/or 6B, each of which may include different sub-components, different memory capacities, I/O capabilities, etc. For example, because some implementations of distributed networking and/or distributed computing are associated with particular desired functionality, examples disclosed herein include different combinations of components illustrated in FIGS. 6A and/or 6B to satisfy functional objectives of distributed computing tasks. In some examples, the term “compute node” or “computer” only includes the example processor 604, memory 606 and I/O subsystem 608 of FIG. 6A. In some examples, one or more objective functions of a distributed computing task(s) rely on one or more alternate devices/structure located in different parts of an Edge networking environment, such as devices to accommodate data storage (e.g., the example data storage 610), input/output capabilities (e.g., the example peripheral device(s) 614), and/or network communication capabilities (e.g., the example NIC 620).

In some examples, computers operating in a distributed computing and/or distributed networking environment (e.g., an Edge network) are structured to accommodate particular objective functionality in a manner that reduces computational waste. For instance, because a computer includes a subset of the components disclosed in FIGS. 6A and 6B, such computers satisfy execution of distributed computing objective functions without including computing structure that would otherwise be unused and/or underutilized. As such, the term “computer” as used herein includes any combination of structure of FIGS. 6A and/or 6B that is capable of satisfying and/or otherwise executing objective functions of distributed computing tasks. In some examples, computers are structured in a manner commensurate to corresponding distributed computing objective functions in a manner that downscales or upscales in connection with dynamic demand In some examples, different computers are invoked and/or otherwise instantiated in view of their ability to process one or more tasks of the distributed computing request(s), such that any computer capable of satisfying the tasks proceed with such computing activity.

In the illustrated examples of FIGS. 6A and 6B, computing devices include operating systems. As used herein, an “operating system” is software to control example computing devices, such as the example Edge compute node 600 of FIG. 6A and/or the example Edge compute node 650 of FIG. 6B. Example operating systems include, but are not limited to consumer-based operating systems (e.g., Microsoft® Windows® 10, Google® Android® OS, Apple® Mac® OS, etc.). Example operating systems also include, but are not limited to industry-focused operating systems, such as real-time operating systems, hypervisors, etc. An example operating system on a first Edge compute node may be the same or different than an example operating system on a second Edge compute node. In some examples, the operating system invokes alternate software to facilitate one or more functions and/or operations that are not native to the operating system, such as particular communication protocols and/or interpreters. In some examples, the operating system instantiates various functionalities that are not native to the operating system. In some examples, operating systems include varying degrees of complexity and/or capabilities. For instance, a first operating system corresponding to a first Edge compute node includes a real-time operating system having particular performance expectations of responsivity to dynamic input conditions, and a second operating system corresponding to a second Edge compute node includes graphical user interface capabilities to facilitate end-user I/O.

The instructions 682 may further be transmitted or received over a communications network using a transmission medium via the wireless network transceiver 466 utilizing any one of a number of wireless local area network (WLAN) transfer protocols (e.g., frame relay, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), Plain Old Telephone (POTS) networks, and wireless data networks. Communications over the networks may include one or more different protocols, such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi, IEEE 802.16 family of standards, IEEE 802.15.4 family of standards, a Long Term Evolution (LTE) family of standards, a Universal Mobile Telecommunications System (UMTS) family of standards, peer-to-peer (P2P) networks, a next generation (NG)/5th generation (5G) standards among others.

In these embodiments, the combination of hardware elements and program code may be referred to as a particular type of circuitry.

The term “processor circuitry” or “processor” as used herein thus refers to, is part of, or includes circuitry capable of sequentially and automatically carrying out a sequence of arithmetic or logical operations, or recording, storing, and/or transferring digital data. The term “processor circuitry” or “processor” may refer to one or more application processors, one or more baseband processors, a physical central processing unit (CPU), a single- or multi-core processor, and/or any other device capable of executing or otherwise operating computer-executable instructions, such as program code, software modules, and/or functional processes.

FIG. 7 illustrates an example software distribution platform 705 to distribute software, such as the example computer readable instructions 682 of FIG. 6B, to one or more devices, such as example processor platform(s) 710 and/or example connected Edge devices. The example software distribution platform 705 may be implemented by any computer server, data facility, cloud service, etc., capable of storing and transmitting software to other computing devices (e.g., third parties, the example connected Edge devices). Example connected Edge devices may be customers, clients, managing devices (e.g., servers), third parties (e.g., customers of an entity owning and/or operating the software distribution platform 705). Example connected Edge devices may operate in commercial and/or home automation environments. In some examples, a third party is a developer, a seller, and/or a licensor of software such as the example computer readable instructions 682 of FIG. 6B. The third parties may be consumers, users, retailers, OEMs, etc. that purchase and/or license the software for use and/or re-sale and/or sub-licensing. In some examples, distributed software causes display of one or more user interfaces (UIs) and/or graphical user interfaces (GUIs) to identify the one or more devices (e.g., connected Edge devices) geographically and/or logically separated from each other (e.g., physically separated IoT devices chartered with the responsibility of water distribution control (e.g., pumps), electricity distribution control (e.g., relays), etc.).

In the illustrated example of FIG. 7 , the software distribution platform 705 includes one or more servers and one or more storage devices. The storage devices store the computer readable instructions 682. The one or more servers of the example software distribution platform 705 are in communication with a network 715, which may correspond to any one or more of the Internet and/or any of the example networks described above. In some examples, the one or more servers are responsive to requests to transmit the software to a requesting party as part of a commercial transaction. Payment for the delivery, sale and/or license of the software may be handled by the one or more servers of the software distribution platform and/or via a third-party payment entity. The servers enable purchasers and/or licensors to download the computer readable instructions 682 from the software distribution platform 605. For example, the software, which may correspond to the example computer readable instructions, may be downloaded to the example processor platform(s) 700 (e.g., example connected Edge devices), which is/are to execute the computer readable instructions 682 to implement the content insertion at a switch. In some examples, one or more servers of the software distribution platform 705 are communicatively connected to one or more security domains and/or security devices through which requests and transmissions of the example computer readable instructions 682 must pass. In some examples, one or more servers of the software distribution platform 705 periodically offer, transmit, and/or force updates to the software (e.g., the example computer readable instructions 682 of FIG. 6B) to ensure improvements, patches, updates, etc. are distributed and applied to the software at the end user devices.

In the illustrated example of FIG. 7 , the computer readable instructions 682 are stored on storage devices of the software distribution platform 705 in a particular format. A format of computer readable instructions includes, but is not limited to a particular code language (e.g., Java, JavaScript, Python, C, C#, SQL, HTML, etc.), and/or a particular code state (e.g., uncompiled code (e.g., ASCII), interpreted code, linked code, executable code (e.g., a binary), etc.). In some examples, the computer readable instructions 682 stored in the software distribution platform 705 are in a first format when transmitted to the example processor platform(s) 710. In some examples, the first format is an executable binary in which particular types of the processor platform(s) 710 can execute. However, in some examples, the first format is uncompiled code that requires one or more preparation tasks to transform the first format to a second format to enable execution on the example processor platform(s) 710. For instance, the receiving processor platform(s) 710 may need to compile the computer readable instructions 682 in the first format to generate executable code in a second format that is capable of being executed on the processor platform(s) 710. In still other examples, the first format is interpreted code that, upon reaching the processor platform(s) 710, is interpreted by an interpreter to facilitate execution of instructions.

FIG. 8 illustrates an example information centric network (ICN), according to an embodiment. ICNs operate differently than traditional host-based (e.g., address-based) communication networks. ICN is an umbrella term for a networking paradigm in which information and/or functions themselves are named and requested from the network instead of hosts (e.g., machines that provide information). In a host-based networking paradigm, such as used in the Internet protocol (IP), a device locates a host and requests content from the host. The network understands how to route (e.g., direct) packets based on the address specified in the packet. In contrast, ICN does not include a request for a particular machine and does not use addresses. Instead, to get content, a device 805 (e.g., subscriber) requests named content from the network itself. The content request may be called an interest and transmitted via an interest packet 830. As the interest packet traverses network devices (e.g., network elements, routers, switches, hubs, etc.)—such as network elements 810, 815, and 820—a record of the interest is kept, for example, in a pending interest table (PIT) at each network element. Thus, network element 810 maintains an entry in its PIT 835 for the interest packet 830, network element 815 maintains the entry in its PIT, and network element 820 maintains the entry in its PIT.

When a device, such as publisher 840, that has content matching the name in the interest packet 830 is encountered, that device 840 may send a data packet 845 in response to the interest packet 830. Typically, the data packet 845 is tracked back through the network to the source (e.g., device 805) by following the traces of the interest packet 830 left in the network element PITs. Thus, the PIT 835 at each network element establishes a trail back to the subscriber 805 for the data packet 845 to follow.

Matching the named data in an ICN may follow several strategies. Generally, the data is named hierarchically, such as with a universal resource identifier (URI). For example, a video may be named www.somedomain.com or videos or v8675309. Here, the hierarchy may be seen as the publisher, “www.somedomain.com,” a sub-category, “videos,” and the canonical identification “v8675309.” As an interest 830 traverses the ICN, ICN network elements will generally attempt to match the name to a greatest degree. Thus, if an ICN element has a cached item or route for both “www.somedomain.com or videos” and “www.somedomain.com or videos or v8675309,” the ICN element will match the later for an interest packet 830 specifying “www.somedomain com or videos or v8675309.” In an example, an expression may be used in matching by the ICN device. For example, the interest packet may specify “www.somedomain.com or videos or v8675*” where ‘*’ is a wildcard. Thus, any cached item or route that includes the data other than the wildcard will be matched.

Item matching involves matching the interest 830 to data cached in the ICN element. Thus, for example, if the data 845 named in the interest 830 is cached in network element 815, then the network element 815 will return the data 845 to the subscriber 805 via the network element 810. However, if the data 845 is not cached at network element 815, the network element 815 routes the interest 830 on (e.g., to network element 820). To facilitate routing, the network elements may use a forwarding information base 825 (FIB) to match named data to an interface (e.g., physical port) for the route. Thus, the FIB 825 operates much like a routing table on a traditional network device.

In an example, additional meta-data may be attached to the interest packet 830, the cached data, or the route (e.g., in the FIB 825), to provide an additional level of matching. For example, the data name may be specified as “www.somedomain.com or videos or v8675309,” but also include a version number—or timestamp, time range, endorsement, etc. In this example, the interest packet 830 may specify the desired name, the version number, or the version range. The matching may then locate routes or cached data matching the name and perform the additional comparison of meta-data or the like to arrive at an ultimate decision as to whether data or a route matches the interest packet 830 for respectively responding to the interest packet 830 with the data packet 845 or forwarding the interest packet 830.

ICN has advantages over host-based networking because the data segments are individually named This enables aggressive caching throughout the network as a network element may provide a data packet 830 in response to an interest 830 as easily as an original author 840. Accordingly, it is less likely that the same segment of the network will transmit duplicates of the same data requested by different devices.

Fine grained encryption is another feature of many ICN networks. A typical data packet 845 includes a name for the data that matches the name in the interest packet 830. Further, the data packet 845 includes the requested data and may include additional information to filter similarly named data (e.g., by creation time, expiration time, version, etc.). To address malicious entities providing false information under the same name, the data packet 845 may also encrypt its contents with a publisher key or provide a cryptographic hash of the data and the name Thus, knowing the key (e.g., from a certificate of an expected publisher 840) enables the recipient to ascertain whether the data is from that publisher 840. This technique also facilitates the aggressive caching of the data packets 845 throughout the network because each data packet 845 is self-contained and secure. In contrast, many host-based networks rely on encrypting a connection between two hosts to secure communications. This may increase latencies while connections are being established and prevents data caching by hiding the data from the network elements.

Example ICN networks include content centric networking (CCN), as specified in the Internet Engineering Task Force (IETF) draft specifications for CCNx 0.x and CCN 1.x, and named data networking (NDN), as specified in the NDN technical report DND-0001. It is understood that an ICN network may be implemented on top of or in combination with other types of networks, such as IP networks. For instance, an ICN network may use IP networks for backhaul.

FIG. 9 is a diagram illustrating an operating environment 900, according to an embodiment, according to an embodiment. The operating environment 900 includes NFN/NDN nodes 902A, 902B, . . . , 902N (collectively referred to as 902). A user device 904 is connected to the nodes 902 via a network 906. User device 904 may be a user equipment (UE), and may be any device used directly by an end-user to communicate. It may be a mobile telephone, smartphone, laptop computer equipped with a mobile broadband adapter, desktop computer, kiosk, or any other device. The nodes 902 are connected to the network and provide support for NFN and NDN functionality. The nodes 902 may be associated with one another. In an embodiment, the nodes 902 are part of a blockchain network.

One or more function providers (FP) 908A, 908B, . . . , 908N (collectively referred to as FP 908) are connected via an NFN network 910. The NFN network 910 may be a portion of network 904. The FP 908 are repositories for functions that are available via NFN networking. The FP 908 may execute the function on behalf of the user device 904. Alternatively, the FP 908 may respond to an interest packet for a function with the names of functions that match the query in the interest packet. For instance, the interest packet may express an interest in a function name of “function1*” and the response data packet may include a list of “function1_v1” and “function1_v2”.

One or more data providers (DP) 912A, 912B, . . . , 912N (collectively referred to at DP 912) are connected via an NDN network 914. The NDN network 914 may be a portion of network 904. The DP 912 are repositories for data that are available via NDN network 914, content delivery network (CND), or ICN networking. It is understood that DP 912 and FP 908 may be part of the same system, hosted by the same provider, or otherwise related.

A network administrator device 916 is used to configure a filter 918 that is stored at the NFN/NDN nodes 902. The filter 918 includes a denylist and may include a permitlist. The denylist includes functions and corresponding metadata defining characteristics (e.g., version or edition number) of functions that are not allowed to be returned in response to an interest packet. The metadata may include other data, such as the type of resource targeting the function (e.g., FPGA, CPU, etc.), the type of deployments where the function is meant to be executed (e.g., base station, on-premise server, etc.), characteristics of an SLA associated with the function (e.g., performance boundaries or requirements), and the like. The characteristics of the SLA may be a list of discrete values.

Entries in the denylist and the permitlist (if one is used) may be NFN functions that are described using a standardized data definition language. Definition languages such as Concise Software Identification (CoSWID) Tags, Concise Module Identifier (CoMID) language, or Concise Reference Integrity Manifests (CoRIM) language may be used to describe functions, platforms, and other aspects of named-function networks. For instance, the tags may be used to record unique information about a function, including its name, edition, version, signature hash, etc. The entries in the denylist and the permitlist may be stored together in a registry. A signature hash, or hash, is a way of uniquely identifying applications or executables. Code may be combined with one or more other metadata values, and then the combination is hashed to produce a signature. For instance, the code and version number may be combined and then hashed to produce a unique signature of that version of the code. Using the hash to compare code ensures that potentially malicious code can still be identified even when masked in various ways.

NFN functions may be cataloged in a registry that lists all the NFN functions available in the NFN. An NFN function is conditionally added to the registry if its attestation and reputation are determined to be acceptable. Attestation establishes manufacturer provenance while reputation establishes the behavior pattern it exhibited from prior executions.

In a staged deployment of new functions in the NFN network 910, a sandbox environment may be used to run unknown functions to observe the function's behavior. For example, the set of system calls it invokes, resource allocations, and network endpoints it connects to can be monitored and included into the reputation report. The reputation report may be incorporated into the registry using a standardized data definition language. Container technology such as K8S, Kata, SGX, TDX, and FPGA designs can be used to isolate execution. Companion/side-car enclaves, trusted domains, containers, etc. can be used to drive workloads aimed at exercising all the code paths through black box fuzzing or white box workloads that an independent vendor generates based on white box code analysis techniques.

The reputation reports may be archived to guarantee their integrity in heterogenous stakeholder environments. This archive may be stored in a blockchain. A central trusted entity may be used to perform the archival.

In operation, a network administrator device 916 is used to configure a filter 918 that is stored at the NFN/NDN nodes 902. Functions may have versions that become outdated, may be identified as potentially malicious or untrustworthy, or may be associated with potentially malicious or untrustworthy providers. Such functions are added to a denylist.

In some implementations, the filter 918 is a running list of transactions to add or remove functions from a ledger, which may be stored in a blockchain. The blockchain may be associated with a group of user devices, edge appliances, or other devices. There may be several blockchains, one for each group of devices, such that different blockchains are accessible or created for different groups of devices. Different blockchains may be administered per domain or per groups of tenants, where each group may have different policies.

NFN/NDN nodes 902 may manage the blockchain by adding blocks to the blockchain, with each block including one or more transactions to the filter 918 to add or remove entries in the filter 918.

A network user seeking to perform a function (Fn) using data named Data1 and Data2 constructs an NFN interest packet 920 containing the function name and the data names. The interest packet 920 is sent to one or more NFN/NDN nodes 902. An NFN/NDN node 902 receives the interest packet 920, decomposes the interest packet 920 to obtain the function name and any data names, and then uses the function and data names to obtain the executable and the data. The NFN/NDN node 902 constructs an NFN interest packet 922 and transmits it over the NFN network 910 to the function providers 908. The function providers 908 respond with specific names of functions that they have in their respective repositories. For instance, the NFN interest packet 922 may use a function name of “Function1*” and an FP 908 may have several versions of “Function1” and respond with a data packet including “Function1_v1” and “Function1_v3”.

Similarly, the NFN/NDN node 902 sends one or more data interest packets 924 to one or more data providers 912 over NDN network 914 for the data names in the interest packet 920. Data providers 912 that have the data named in the data interest packet 924 respond with data packets including the path or name of the data.

The NFN/NDN node 902 now has the available versions or editions of the requested function and the locations of the data for use in the function. The NFN/NDN node 902 applies the filter 918 to remove any functions that are on the denylist and then constructs a responsive data packet that includes the function names of those that are not filtered out. The filter 918 may have references to entries in a registry of NFN functions. Alternatively, the filter 918 may include function signatures. After excluded function names are remove, a responsive data packet with the functions that have passed is sent in response to the initial NFN interest packet 920. The network user may then select the function version that they want to execute and initiate execution.

The filter 918 may also implement a permitlist. The permitlist may have references to entries in a registry of NFN functions. For instance, the remaining available functions are compared to those listed in a permitlist. If only one of the functions is on the permitlist, then that function is the one executed. However, if both functions are on the permitlist, then other selection criteria (e.g., recency, build date, version, reputation score, etc.) may be used to decide which function to use.

The filter 918 may also use reputation of a function to determine whether a function is permissible. A base reputation score may be assigned after a function is analyzed in a sandboxed environment. The function is analyzed in a sandbox to contain any potential malicious activity. A base score, such as “1.0” may be assigned to a new function. Only those functions with reputation scores may be added to a permitlist. As the function is used, the reputation score may be increased to show its reliability or trustworthiness. The reputation score may be increased if the function performs successfully, provides accurate results, performs according to SLA requirements, or the like. The reputation score may be part of the function's metadata and stored in a registry. The registry may be recorded in a centralized location, which may be secured. In an implementation, the registry may be stored in a blockchain. The registry blockchain may be per group, per domain, per device, etc.

Alternatively, instead of sending a list of available functions to the network user, the NFN/NDN node 902 orchestrates execution of the function with the data and then returns the result of the function to the network user in a data packet. The NFN/NDN node 902 may use various selection criteria to determine which function to execute. For instance, if there are three versions that are returned from the function providers 908, and one of them is on the denylist, then the NFN/NDN node 902 may use a process that selects the most current version of the remaining options. So, if the two remaining options are version 3 and version 7, then the NFN/NDN node 902 will use version 7. As another example, if the two remaining options have build dates of “3/7/2000” and “11/4/2001”, then the NFN/NDN node 902 may use the 2001 build. Permitlists and reputation may also be used as factors in selecting a function to execute.

In an example use case, given a function Fn with parameters Data1 and Data2 represented as Fn(Data1, Data2) with hash=“ABC” from function provider 1. The same function Fn(Data1, Data2) is also available with hash =“XYZ” from function provider 2. On the NFN/NDN node, if the function with hash=“XYZ” is delivering the wrong results, this function with the corresponding hash is added to the denylist. The hash of this function can be graded and added to or updated in a block in a blockchain. If the function with hash=“ABC” is providing correct results, the reputation of this function may be increased.

As another example use case, in an NFN network, a user intends to convert some raw data to MPEG format and submits an interest packet. The nearest NFN node intercepts the packet and downloads the MPEG converters. If the user is presented with the choices, an expert user may select DivX as an example, because it is more reputable than a less known application. On the other hand, if the user is not an expert but a regular person who just wants to convert the raw data to MPEG, the reputation method is used to select the function that has not been denylisted and the NFN node executes the function on the user's behalf.

FIG. 10 is a flowchart illustrating a method 1000 for filtered named-function networking, according to an embodiment. At 1002, a user requests a function by name in an interest packet. The interest packet includes the data upon which the function is to act. At 1004, an NFN node deconstructs the interest packet and downloads the function and data from providers. At 1006, for each function returned from the function provider(s), the NFN node checks to see if the function is on a denylist. If the function is on the denylist, then the method proceeds back to 1004 to obtain the next function to check. If the function being checked is not on the denylist, then at 1008, the function is executed by the NFN node. The NFN node may initiate execution on another processing node or perform the execution at the NFN node. At 1010, the results of the function's execution are checked to ensure that the results are acceptable (e.g., in an acceptable range of values, or does not cause an error or exception while executing). If the function results are not acceptable, then the function is added to the denylist (operation 1012) and the next version of the function is retrieved for permitlist checking and execution. If the function results are acceptable, then the results are provided to the user (operation 1014).

FIG. 11 is a flowchart illustrating another method 1100 for filtered named-function networking, according to an embodiment. The method 1100 may be performed by a compute node, or by another device, such as NFN/NDN nodes 902 or an Edge computing node 650.

At 1102, an information centric network (ICN) interest packet from a user device is accessed, the ICN interest packet including a function name and a data name. At 1104, a named-function network (NFN) interest packet is constructed using the function name. At 1106, the NFN interest packet is transmitted to a function provider. At 1108, an NFN data packet is received with a version of a function corresponding to the function name At 1110, a named-data network (NDN) interest packet is constructed using the data name At 1112, an NDN data packet is received with a data value corresponding to the data name.

At 1114, it is determined that the version of the function is not on a denylist. In an embodiment, the denylist is stored in a blockchain. In an embodiment, the denylist includes function names and corresponding hashes of the functions that are not allowed to execute. In an embodiment, the denylist is stored in a blockchain associated with a group of user devices, the blockchain one of multiple blockchains for respective groups of user devices. In an embodiment, the compute node is a member of a blockchain network corresponding to the blockchain.

At 1116, execution of the version of the function with the data value is initiated in response to determining that the version of the function is not on the denylist. In an embodiment, initiating execution includes constructing a response data packet to the user device, the response data packet including the version of the function and the data value. In an embodiment, initiating execution comprises orchestrating execution of the version of the function using the data value.

In an embodiment, the method 1100 includes determining that the version of the function is on a permitlist. In such an embodiment, initiating execution is in response to determining that the version of the function is on the permitlist. In an embodiment, the permitlist includes function names and corresponding hashes that are allowed to execute.

In an embodiment, the method 1100 includes monitoring execution of the version of the function to identify correct operation and increasing a reputation score of the version of the function in response to identifying correct operation.
